The goal of this project was to determine whether recombinant porcine (rp) prolactin (PRL) can enhance mammary development when given to pre-pubertal gilts and/or modify the expression of PRL-related genes. Crossbred gilts were injected s.c. twice daily with saline (CTRL; n = 13), 2 mg of rpPRL (4PRL; n = 13), or 4 mg of rpPRL (8PRL; n = 13) in a 2.0-mL volume for a period of 29 d, starting at 75.1 +/- 0.5 kg BW. Jugular blood samples were collected before the first injection, as well as 14 and… CONTINUE READING
